摘要：
We suggest that the combined effect of screening, gluon-induced dissociation, collisional damping, and reduced feed-down explains most of the sequential suppression of Upsilon(nS) states that has been observed in PbPb relative to pp collisions at root s(NN) = 2.76 TeV. The suppression is thus a clear, albeit indirect, indication for the presence of a qgp.
